Hessen is to receive 100,000 additional Moderna vaccination doses on Thursday.
The acting Federal Health Minister Jens Spahn (CDU) and Hesse's Health Minister Kai Klose (Greens) announced on Wednesday evening.
"This additional delivery will help ensure that the vaccination campaign continues to gain momentum," said the ministers.
Spahn's spokesman Hanno Kautz had previously said in a "Bild" report: "The state of Hesse will pick up 100,000 vaccine doses from Moderna tomorrow in the central warehouse of the federal government."
In the past few days there had been resentment about the shortage of vaccines in Hesse. The family doctors in Hesse, for example, were "pissed off" at the politics in Berlin. The fact that not enough corona vaccine is arriving in the practices now is "a complete disaster," said the chairman of the Hesse family doctors' association, Armin Beck, of the German press agency on Wednesday. "This is an organizational meltdown." The mood is tense, "you could also say shitty".
In the vaccination center of Hesse's largest city, Frankfurt, the vaccine threatened to run out on Tuesday.
The situation was "tense", a spokeswoman for the health department said on Tuesday.
The city had already restricted offers such as the vaccination express and canceled special vaccination campaigns on Monday evening.
"All of Frankfurt is pissed off at Berlin," said Mayor Peter Feldmann (SPD).
Instead of the 19,380 doses ordered, Hesse's largest city only received around 6,000 doses of the Comirnaty vaccine from Biontech and a maximum of 4,000 doses of Spikevax from Moderna, it said.
The Main-Kinzig district also reported the first problems in the vaccination centers.
